Hi @haspear,


I'd like to help!


To assist better -


Are you trying to scan to email?

What is the status of the wireless light on the printer, steady or blinking?

Is the printer connected to a private or public network?


While you respond to that, Let's try a power reset on the printer


Reset the product


With the printer turned on, disconnect the power cord from the rear of the printer.

Unplug the power cord from the wall outlet.

Wait at least 60 seconds.

Plug the power cord back into the wall outlet.

Reconnect the power cord to the printer.

Turn the printer on. HP recommends plugging the printer directly into a wall outlet.


 Also, try updating the printer's firmware -HP Printers - Updating or Upgrading Printer Firmware  


Hope this helps! Keep me posted.
